If a chromosome divides in an axis perpendicular to usual axis of division it is going to form:
**Core Concept**
Chromosomal abnormalities during cell division can lead to various types of genetic disorders. An abnormal axis of division, specifically a perpendicular axis, disrupts the usual pattern of chromosome separation, resulting in an aberrant chromosomal structure.
**Why the Correct Answer is Right**
When a chromosome divides in an axis perpendicular to its usual axis, it can lead to a phenomenon known as a **roolet formation**. This is a type of chromosomal abnormality where the chromosome is split in an abnormal direction, resulting in a characteristic "roolet" appearance under microscopic examination. The perpendicular axis of division disrupts the normal process of sister chromatid separation, leading to the formation of this aberrant structure.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is not relevant to the scenario described, as it does not directly relate to the abnormal axis of chromosome division.
* **Option B:** This option might be related to chromosomal abnormalities, but it does not specifically describe the outcome of a chromosome dividing in a perpendicular axis.
* **Option C:** This option is incorrect because it is not a recognized term in the context of chromosomal abnormalities during cell division.
**Clinical Pearl / High-Yield Fact**
When examining chromosomal preparations under the microscope, it's essential to note any abnormalities in the axis of chromosome division, as these can indicate underlying genetic disorders. A perpendicular axis of division, leading to roolet formation, is a specific red flag that warrants further investigation.
**Correct Answer: C.
